If you’re interested in a tiny backyard studio, getaway, or even a place to live – but you don’t have the money to get started – take some notes from Derek Diedricksen. This builder has not only created a series of incredible tree houses, he has also proven that all you need to get started is $200, some reclaimed junk and a lot of ingenuity.

Diedricksen’s $200 microhomes make use of the most surprising materials, like windows made of pickle jars, wine bottles and round glass from washing machines. Scouring yard sales and junk yards for potential building elements, Diedricksen has managed to make use of frying pan bases, broken brass cymbals and plastic water coolers.

These homes may be on the opposite end of the spectrum from the sleek, modern, architect-designed tiny houses that are a bit easier on the eyes, but they’re also as close to free as it gets. Diedricksen has a menagerie of his own designs hanging out in his backyard, a testament not only to his own boundless energy and inspiration but to how accessible they can be for people who don’t have deep pockets.
